did some observing... when i put snd_hdsp in the RTIRQ_NAME_LIST in the rtirq config, neither priorities nor IRQs change. however... for ALL kernels under which jack fails: /etc/init.d/rtirq status shows irq/19-snd_hdsp AND irq/19-firewire and for the one kernel under which jack works: /etc/init.d/rtirq status shows irq/19-snd_hdsp and a DIFFERENT irq for firewire this seems significant. and... how can i ensure firewire gets a different irq? for now, i'll try killing the firewire module, since i don't use anything firewire at the moment. cheers! .pltk. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
